Does good drinking water mean good growing water?

My city is known for its excellent drinking water, does that mean it's ideal for growing? I know plants have different needs than people. I read it at 250ppm (.5) and from this link they say the same.

Could anyone in the know, take a look at this and see what ya think?

Your water looks great man

Looks great for growing? I know its good to drink for cotton mouth

my tap is same ppm no prob

Yes,, you local water keeps you local plants alive. Pot will grow.. can you make it better YES/.. but is 98% to 99% worth your time and money for better water.

Thats 350 ppm on a .7 meter. You will most likely have issues if you are growing hydroponically, but maybe not. Only one way to find out.

U.S Classification for water ........On .5 scale ...Soft water 0-60 ppm..... moderatly hard 61-120 ppm...... Hard 121-180 ppm....Very hard 181- up ppm

I have seen some impressive grows using very hard water .. Hydro included !

I've been growing for a couple years now in hydro and it seems to work just fine.

Does anyone see a need for a calmag type product? I do get some pretty brown leaves from time to time. The water chart I posted doesn't include either.
